GRUNDMAN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE STAR LAMP COMPANY, OF SAME PLACE.

LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 656,968, dated August 28, 1900. Application filed October 2, 1899. Serial No. 732,330. (No model.)

To all 1071,0717, it may concern:

Be it known that I, FREDERICK W. GRUND- MAN, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a full, clear, and exaot'description, reference being had to the accompanying drawings, forming a part hereof.

my invention relates to lamp-burners; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

The object of this invention is to provide a separable lamp-burner having an improved separable wick-tube and an improved means of attaching the burner to the attachment supporting the burner to the lamp.

Figure MS a side view of the burner when open. Fig. 2 is a top View of the same. Fig. 3 is an inverted view of the burner when closed. Fig. 4 is an enlarged view showing the construction of the wick-tube. Fig. 5 is a top view of an attachment supporting the burner to the lamp when said attachment is open. Fig. 6 is a side view of the same. Fig. '7 shows that my invention may be applied to a non-separable burner by making it separable by sawing along the lines a a and b b.

In the construction of the device, as shown, I provide a separable lamp-burner, as shown in Fig. 1, having a separable wick-tube 1. Side 2 separates from side 3when the burner is opened on the hinge 4. The side 3 has its edges 5 turned inwardly, so that they form a hook or clasp 6 on each edge so constructed that they clasp and hold the wick when side 2 is pulled away by opening the burner. The edges 7 of side 2 extend outwardly and around the hooks or clasps 6 when the burner is closed. It is evident that the wick-tube 1 may be so large that the air may pass into the lamp through said wick-tube or that a separate air-passage 8 may be provided, as shown by dotted lines in Fig. 4.

The burner is provided with an integral non-separable screw-threaded base 9, into which screws the top 10 of the supporting attachment. (Shown in Figs. 5 and 6.) It is evident that the screw-threaded base 9 may be made to attach directly to the lamp. To the lower part of the movable side of the burner are attached hooks or clasps 11, which clasp under the outwardly-projecting top 12 of the screw-threaded base 9 when the burner is closed.

A burner having a separable screw-threaded base may be used. For this I provide a separable top 10 to the supporting attachment. It may be separable along anyline c c or d d and made to open on a hinge 13, specially provided. This may be used with a burner having either a separable or a nonseparable screw-threaded base.

Fig. 7 shows that a non-separable burner may be converted into a separable burner by sawing along the lines a a and b b and attaching a hinge to said burner similar to hinge 4 in Fig. 1.

When it is desired to fill the lamp, the burner is opened, as shown in Figs. 1 and 2, the wick is held securely in position by the clasps 6,and the lamp maybe filled through the aperture 14.

I claim- 1. A separable lamp-burner, having a separable wiok-tube of two parts one of which is rigidly attached to each part of said burner, one of said parts having hooks or clasps for encircling the wick and holding the same in position when the said burner is opened, and the other of said parts being arranged to inclose the said hooks, substantially as specified.

2. A separable lamp-burner of two parts pivoted together and having a non-separable screw-threaded base integral with one of said parts for attaching said burner to the top of the supporting attachment, substantially as and for the purpose described.

3. A separable lamp-burner, comprising two separable parts pivoted together and having a non-separable screw-threaded base integral with one of said parts and hooks or clasps on the under side of the other'of said parts for attaching said part to said non-separable screw-threaded base when said burner is closed, substantially as and for the purpose specified.

4. In a separable lamp-burner, of two parts pivoted together, a non separable screwihreaded base integral with one of said parts for attaching said burner to the top of the lamp, and hooks or clasps on the other part of said burner for attaching said movable portion to said integral non-separable screwthreaded base, substantially as specified.

5. In a separable lamp-burner, a supportin g attachm ent comprising two hi n ged threadin presence of tWo witnesses.
